  On the last day of last year, China informed World Health Organisation was a cluster of pneumonia cases in Wuhan, caused by a novel coronavirus, which was identified as SARS CoV 2 based on sequences of viral agent available by 10th January 2020 and RT PCR tests developed to identify this RNA virus. The disease caused by this virus was labelled as Covid 19. The rapid spread of this virus from China to all parts of the world including India, led this outbreak to be labelled as a pandemic.

  In January 2020, India had only one laboratory testing for Covid 19, at the Indian Council of Medical Research’s National Institute of Virology, Pune. In Mid May, the testing facilities had been ramped upto 550 laboratories, both in the government and private set up, across the country, performing molecular tests for diagnosis of Covid 19 - an unparallel achievement in the history of Indian health system.

  In the absence of an effective treatment, prevention is the best strategy, which resolves around testing. RT PCR for Covid 19 involves multiple complex steps. This paper describes the minimal steps each performing laboratories must take to ensure quality in their testing. It is essential that testing laboratory verify manufacturer’s claim and perform ongoing monitoring of tests to ensure that reliable and reproducible results are available to decision makers to make evidence based informed decisions for containment of this infection. While EQAS has been announced, but no sample has yet been circulated. Interlaboratory comparison should be encouraged between ICMR designated Reference laboratories and other performing laboratories.
